10.2.4 VLAN Control Registers
Register Name:
Register Description:
Register Address:
080h:
Default
This register is used to control the VLAN Table. The Initialization function resets all of the 4096 entries in the VLAN
Table to their default value.
Bit 2: Control Table Enable (CTE) When equal to zero, the VLAN Table is fully enabled. When set to 1, the VLAN
Table is only enabled as required by the LAN Extract (LAN-VLAN Trap), WAN Extract (WAN-VLAN Trap), or
microprocessor operations.
Bit 1: Control Initialization (CI). A transition from zero to one starts the VLAN Table initialization by resetting all
VLAN table addresses to their default values. A device reset will also trigger a VLAN Table initialization.
Bit 0: Control Auto Increment Mode (CAIM). When set to 1, the VLAN Table Address in SU.VTAA is
automatically incremented with each read or write of the SU.VTWD or SU.VTRD registers.
Register Name:
Register Description:
Register Address:
082h:
Default
The data that is stored at the specified VLAN Table address is automatically loaded into the read register for this
configuration register address. This is true whether the user is performing a read or write function. The user may
choose to read the data (for the read operation) or disregard the data (for the write operation).
Bits 0-11: VLAN Table Access Address (VTAA [12:1]). This register provides the VLAN Table Address for a uP
Read or Write operation.
